FEED-WATER H EATER.

Applic\at'ion filedsepteniher .25, 1883. (No model.)

T0 at whom it may concern Beit known that I, FRANK JAMES Konrn,

of Zanesville, county of Musk'ingum, State of -Ohio, have invented a new and useful Improvement in Feed-Water Heaters; and I de-' clare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form a part of this specification.

My invention consists in the combinations of devices and appliances hereinafter specified, and more particularly pointed out in the claims.

In the drawings, Figure 1 is a perspective view of a boiler embodying my invention. Fig. 2 is alongitudinal sectional view, showing a modification of the invention. Fig. 3 is a longitudinal section. Fig. 4 is a separate view Fig. 5 is a sectional view of Fig. 1. a

It is the object of my invention to'construct a feed-water heater in sizes suitable for insertion within the smoke-box at the end of the boiler adjacent to the smoke-stack oruptake, so as to be heated with the waste heat of the products of combustion as they escape from the boiler fiues or tubes and are about to pass to the chimney-flue.

. My invention also has for its object the construction of this feed-Water heater sorthat it shall swing out upon a hinge, the same as the ordinary door located at this point, so as to give readyaccess to the boiler fines or tubes, in case it is desired to get atthem for cleaning or repairs. I

In the accompanying drawings, which are designed simply to illustrate my invention, A is an ordinary horizontal boiler. B is the furnace; A, the boiler flues or tubes. 0 is the smoke-box; D, the chimney or uptake.

Erepresents myimproved feed-water heater. It is of such size and dimensions as to fit within the end of the smoke-box, although, instead of fitting within the end, it may be adapted so as to fit against the end. It is, provided with two or more interior partitions, E. Two are represented in the drawings, and they divide c is the inlet for the feed-water. e is' the mud-valve or blow-off, and e the exit for the feed-water. The middle space is represented as filled with hay, straw, excelsior, or their equivalent filtering material.

The operation of the device is obvious. Feed-water entering at e is heated by the waste heat of the products of combustion as they escape from the boiler-fines and before passing to the chimney. Being heated, the water deposits the main portion of its sediment in the lower chamber adjacent to the blow-off e. Its remaining impurities and cry'stallizable salts are extracted in passing through the filtering-chamber and the space beyond it, and-the water is discharged in a purified and heated condition from the exite", whence it is pumped into the boiler.

E is a' hinge by which the heater is suspended in its place, thus making'the heater to serve the purpose of a'door for gaining ready access to the boiler flues or tubes. The heater may be provided with man-holes E opposite any or all of its interior chambers, to facilitate the cleansing of the interior or renewal of the filtering material.

I would have it understood that I do not limit myself to a construction in which the heater is hinged to the smoke-box, for it may be simply inserted within or upon the end of the smoke-box, and be secured in any convenient way. The inlet or exit pipes for the water may be united with the heater by fiexible pipes or couplings, so as to admit of opening the door without disconnecting the pipes; or they may be rigidly connected, in which case they would have to be unj ointed before opening the heater from the end of the smokebox.

It is my purpose to construct these heaters of different sizes, corresponding-with the different sizes of standard boilers, so that they can be sold in such shape as to be immediately connected with any of the usual sizes of boilers. I purpose to make them of cast metal in a single piece, or to make them of wrought metal in parts riveted together, as may be deemed desirable, or cast steel, brass, or any metal.

This heater may, if preferred, be extended upward through the base of the smoke-stack,

and include said base of the stack within it, as illustrated in the modification shown in Fig. 2, so as to form a part of said stack, said heater being joined to the stack at the top by a suitable joint, the smoke passing through the upper part of the heater.

\Vhat I claim is- 1. The combination, with a boiler smokebox, of a feed-water heater secured thereto, and composed of the chamber having partitions E, a filtering material arranged between the partitions, the in1et-port e, outlet-port c and blow-off port 6, substantially as and for the purposes described.

2. The combination, with a boiler, of a feedwater heater consisting of a chamber constructed to constitute a wall of the smoke-box, said heater hinged to the boiler at this point and serving as a door for gaining access to the tubes and flue, substantially as described.
